Concentrated mildly acidic hard surface cleaning compositions having a superior combination of cleaning and disinfecting comprise, by weight of concentrated composition: from about 0.5 to about 40% amine oxide detergent; from about 0 to about 4% nitrogen-containing chelant; and from about 1 to about 30% quaternary disinfectant. When the concentrated composition is diluted to form a diluted composition having a concentration of amine oxide of 0.5%, at least 10% of the amine oxide detergent within the diluted composition is protonated; the diluted composition has a surface tension of about 27 dynes per cm.sup.2 or less and a pH of from about 3 to about 7. Diluted cleaning compositions prepared from the concentrated compositions comprise from about 40 ppm to about 12,500 ppm of an amine oxide detergent, and from about 50 ppm to about 1500 ppm of a quaternary disinfectant (quat), and have a surface tension of about 27 dynes per cm.sup.2 or less; at least 10% of the amine oxide detergent within the diluted cleaning composition is protonated.
An improvement is described in compositions which are especially effective in disinfecting the surface being cleaned and in the removal of oily and greasy soil which contains a mixture of a disinfecting agent, a booster agent for the disinfecting agent, an anionic surfactant and a hydrocarbon ingredient, a water soluble cosurfactant, and water.
An improvement is described in compositions which are especially effective in disinfecting the surface being cleaned and in the removal of oily and greasy soil without leaving streaks which contains a mixture of at least one nonionic surfactant, a cationic surfactant, an anionic surfactant and a hydrocarbon ingredient, a water soluble solvent, and water.

Acidic hard surface cleaners are disclosed having a disinfectant which is a quaternary ammonium biocide and/or a substituted guanidine biocide such as a biguanide biocide. There is also a cationic polymer and a surfactant which does not have an anionic moiety. Water is also included at the time of use.
